To all whom, it may concern Be it known that I, 'VVILLIAM J A. Lonnomsubjectof King George V, residing at Hartford, county of Hartford, Stateof Connecticut, have inv'entpdfleerta'in new and useful Improvements in Diffusion-vanes. for

Foreed'Draft or other Blower Sets, of

whichthe following is a full, cle a r, and exact description. y ifMy invention relats' to blower 'sets for forced draft and the like, and is particularly concerned with improvements 111 the mannersof mounting-the. fan cone and diffusion vanes for such sets.

The object of the invention is to so'mountthe fan casing and cone, .and also the diffusion vanes relative tothe fan as to produce the mostcom a ctv wnstruction, and which will prevent t. e loss'due to-the large clearance necessary between the tan and its cone or easing, whl'chis necessary in the construetions in common use.

llith these objects. in view, the invention consists in a construct-ion "and arrangementof parts, the preferredembodiment of which is illustrated in the accompanying draw ing in which,

Figure l is :rview particularly in section howing one layout of the fan and its casing in combination with the turbine by which the tan may be operated. the parts being in section. Fig. 2 is a fragmentary View similar to Fig. l of'a modified form of layout. v

This invention is particularly, though not exclusively, adapted for use on shipboard in which installations the fan motor and fan are usually supported on girders or Lbeams within the body of the ship, while the guide vanes or dil'l'usion vanes are secured to the deck of the hr at. In torpedo boats or similar .;-.:sels. the construction of the boatis 0 hint that therois a distinct, movemeht tjietweeu the deck of the boat. and the girders Hp mii'infj the turbine and fan, conseqnently. a large elezu'anee must be allowed beiWe-Ln the fan itself andthe fan (ones 1;! rasings. Insnvh onstruct-ion consul-Enable h.s-;es in :IiPPltSHll'O are found to exist da'u to these iarge elearani'tes, for the reason that the pressure on the outside of tinlaai s g eater than that on the inside s'mzl mt. tl "rui on, there exists a concasing is rigidly held in proper .closely about the fan, and'tha-t, the. an cone I timial eddying or return-of the, high pres sure air through this clearance space.

.Theolqect ofthepresent invention, thereof parts generally. .Re ferring to Fig. 1 'l i'ndieat'es a steam turbine or other suttabl i casing ofwhichis' provided with a convenient 'flange 2, suppO'r'ted'u o'n -gird e'rs or beams .3 conveniently -:1oca ed. within the.

body o'Lthe vessel. Upon thesliaft 4 of this motor. is mounted-the fan whiel l maybe of any de'sired'construct-ioii. I 6 indicates the -fan casing which may beiprovided with any desired number of ditt'usion vanes 7-7 as shown. In the usual'arrangement of aprance and improving the arrangement Patented uly 9, 1912;

e form ofmotor, the

paratus of this character, the fan casing is secured to the deck 8 'of the vessel, and consequently owing to the movement of thedeck relatively to the girders 3,"considerable clearance must. be allowed between the fan and its casing to prevent injury of the parts. In the arrangementhere illustrated, the intake pipe or funnel 9. is secured to'the deck as at 10, in a suitable manner, and the fan casing is provided with a cone 1-1, sli'dably mounted Within the intake pipe 9, and ithe casing as a whole is mounted 'on supporting standards 12, which; in Fig. 1"are sliown as supported directly by the. beams or girders 'It, will-be seen, therefore,t-hat, the fan 'Osition 11 may readily accommodate itself to any movements of the intake pipe Q due to'movement ofthe deck 8. I p

In the embodiment of-the 'i'ngent-ion illus .trated'in Fig. 2, thc'pai'ts are in general of the same construction and arrangement as heretofore described, but in this case, the fan casing and vanes, as well as the fan cone, instead of being-supported directly upon the girders or supporting beams 3 are directly "upon standards 13 on supported the turbine casing 14. 1

\Vh'ile l-have herein described the particular embodimert of my invention, it is to be understood that the same maybe altered in dot ails and relative arrangement of parts within the scope of the. appended claims.

\Vhat I claim is:-

1. In a blower set for \--'essels, thecombi nation with a fan and motor therefor rigidly mounted within the body'of the vessel, an intake pipe supported from the deck of the vessel, a tan casing also rigidly mounted within the body Oillle vessel, and a fan cone connecting said intake pipe and movable relatively thereto.

2. In a blower set for vessels, the combination with a fan and a motor therefor, supportin members within the body of the vessel wit iin which said parts are rigidly mounted, a fan" casing "for said fan also rigidly mounted upon said supporting mem- -a fan and moton-a rigid support for said hers, and "em-intake pipe mounted upon the deck of the vessel and a connection between said intake pipe and said casing slidably mounted relatively tosaid intake ipe.

3. Ina blower set for vessels, t ie combination with a'motor, a fan mounted upon the shaft. of said motor, supporting members within the body of the vessel upon which said motor and fan are" rigidly mounted, a

fan casing for said fan also rigidly mounted within the body of the vessel, an intake pipe mounted upon the deck of the vessel, and a fan cone rigidly connected with said casing and slidably mounted within said intake pipe.

4. In ablower set-, the combination with a fan and motor,'a rigid support for said parts, a casing for said fan also mounted on said support, an intake funnel mounted on a-separate support, and a fan oone rigidly connected with the said fan casing and .movably connected with said intake funnel; 5. In a blower set, the combination with parts, a fan casing rigidly supported relatively to said fan :md motor, an intake funnel IHOUIItGd'UJPOD 'a separate support, and fan cone mounted upon said fan cas- .ing and slidable within said intake funnel.
